4 Introduction

The TPS65986 device is a stand-alone USB Type-C and power-delivery (PD) controller providing cable-

plug and orientation detection at the USB Type-C connector. Upon cable detection, the TPS65986 device

communicates on the CC wire using the USB PD protocol. When cable detection and USB-PD negotiation

are complete, the TPS65986 device enables the appropriate power path and configures alternate mode

settings for internal and (optional) external multiplexers.

This user's guide describes the TPS65986EVM and the capabilities of the EVM with the DP-EXPANSION-

EVM. This guide also contains testing procedures of various PD-power and alternate mode configurations.

The EVM comes with pre-loaded configurations for out of the box functionality and is also customizable

through the TPS6598x Configuration Tool. The TPS65986EVM is a module-based design, allowing the

user to design a custom board to prototype a Type-C PD product using the TPS65986 device. The EVM

has four main connectors which are the Type-C receptacle, barrel-jack power, expansion-board connector,

Setup

SLVUAN9A–June 2016–Revised July 2016

TPS65986 EVM User's Guide

and two BoosterPack headers. The Type-C receptacle is a full-feature port, with power, SSTX, SSRX,

SBU1, SBU2, DP, and DN signals. The TPS65986 device can be used in self-powered and bus-powered

configurations for added flexibility. When self powered, the EVM can provide up to 60 W of power (20 V, 3

A). The EVM is also capable of sinking 60 W of power (20 V, 3 A) when the device is in powered, dead

battery, or consumer mode. The EVM can perform a power-role swap to provide power when the barrel

jack (external power) is connected. The expansion board connector routes the power, SSTX, SSRX,

USB_RP_P, USB_RP_N, AUX_P, AUX_N, HPD, I2C, and GPIO control for the DP-EXPANSION-EVM.

The BoosterPack headers give access to the GPIO, 3.3-V and 5-V rails, SPI pins, I2C, AUX_P, AUX_N,

USB_RP_P, and USB_RP_N. The BoosterPack headers are configured for mounting on any TI MCU

LaunchPad™ development kit. Custom PCBs may be built as a mechanical interface to the Aardvark if the

I2C, SPI, and GND pins of the BoosterPack headers are wired to the associated pins on a 10-pin male

header to mate with the Aardvark.

5 Setup

This section describes the various EVM features and how to test the various configurations.

5.1 Switch, Push Button, Connector, and Test Point Descriptions

5.1.1 S2 Switch Bank

This switch bank is used to configure the EVM with the pre-loaded firmware. A total of 8 configurations are

set by the state of the switches on S2. The top switch represents bit 0 and the bottom switch represents

bit 3. The left position is low and the right position is high when looking at the EVM with the Type-C

receptacle facing down. Bit 0, bit 1, and bit 2 are used for setting the configuration, and bit 3 is reserved

for future use (should always be set low for now). Bit 0, bit 1, bit 2, and bit 3 are connected to GPIO1,

DEBUG3, DEBUG4, and GPIO5 respectively. The high position is pulled up through an 11-kΩresistor to

LD0_3V3, and GPIO1, DEBUG3, DEBUG4, and GPIO5 are pulled down through a 100-kΩresistor.

5.1.1.1 S2: DisplayPort Pin Assignment C to Pin Assignment D Switch

The TPS65986EVM allows for Configuration ID 0 to toggle between 4-lane DisplayPort, 2-lane

DisplayPort, and USB3.0 Multifunction. The first switch in S2 is used to toggle between configurations and

does not change the configuration that was selected within Table 2. When switched to the right position,

the TPS65986EVM changes the configuration to prefer USB3.0 Multifunction and renegotiates the

DisplayPort alternate mode. When switched back to the left position, the TPS65986EVM changes the

configuration to not prefer USB3.0 Multifunction and renegotiates the DisplayPort alternate mode.

5.1.2 S1 HRESET Push-Button

S1 is located on the top-left corner of the EVM, under the Expansion Board Connector. This switch is a

push-button that pulls the HRESET pin (D6), of the TPS65986 device high when pressed. Releasing the

push-button pulls HRESET low again, and the TPS65986 device goes through a hardware reset, which

consists of reloading firmware from the non-volatile memory of the external flash. When changing a

configuration on S2, S1 can be used to reset the TPS65986 device, which loads the updated

configurations without disconnecting power from the EVM.

5.1.3 J4: Barrel-Jack Power Connector

The barrel-jack power connector accepts a 19-V to 20-V DC supply. A standard Dell or HP notebook

adaptor (or similar adaptor) provides the required power. This input provides the PP_HV power rail with

the 19 V to 20 V for high-power PD contracts up to 60 W. Select an appropriate power-capable adapter of

60-W operation. For example, the 130-W Dell part number 492-BBGP could be used.

TPS65986 EVM User's Guide

5.1.3.1 Barrel Jack Detect

The TPS65986EVM is capable of requesting a power-role swap when the barrel jack is connected on an

EVM that is currently bus powered which is valid for the configuration IDs that are capable of delivering

power. The barrel jack voltage is sensed by a comparator, which drives GPIO2 on the TPS65986 device.

For enabling barrel jack detect or other GPIOs, refer to TPS6598x Utilities Tool User Guide and

TPS65982 and TPS65986 Firmware User’s Guide.

5.1.4 TP3 and TP4: GND Test Points

Two GND test points are provided for attaching an oscilloscope, multi-meter, or external load GND. These

test points are connected to the board GND planes through 4 vias.

5.1.5 TP1 and TP2: CC1/CC2 Test Points

These test points can be used to tie a PD protocol analyzer for PD BMC data or to verify the BMC signal

integrity with an oscilloscope (depending on the cable orientation). A multi-meter or oscilloscope can be

used to measure VCONN when an electronically marked Type-C cable is connected. These test points

are not intended to provide an external load on VCONN. Figure 1 shows the BMC data oscilloscope

capture.

Figure 1. TPS65986 BMC Data

5.1.6 TP5: VBUS Test Point

The VBUS test point is used to measure VBUS at the connector.

CAUTION

With PD power possibly going up to 20 V, use caution when connecting and

disconnecting probes on the TPS65986EVM. The VBUS test point is capable of

drawing up to 3 A for an external load.

A PD-power contract with the necessary capability must be negotiated to draw current from the VBUS test

point. Refer to TPS6598x Configuration GUI User Guide for configuration instruction. Figure 2 shows the

VBUS voltage during PD power negotiation.

Figure 2. TPS65986 VBUS Voltage Transition

5.1.7 TP6: PP_HV Test Point

This test point is the same power rail as the barrel jack, and it can be used to either provide power to the

TPS65986EVM or measure the voltage supply for the PP_HV. When a custom configuration is created

using the TPS6598x Configuration Tool, the voltage of PP_HV can be set to a minimum of 12 V for high-

voltage contracts. The pre-loaded TPS65986EVM firmware expects to have 20 V at PP_HV (or on barrel

jack) for the configured power capabilities. The PP_HV test point can also be used to sink power when

acting as a consumer or a bus powered device. PP_HV is capable of sinking up to 3 A when acting as a

consumer.

5.1.8 J2 and J3: BoosterPack Headers

These headers allow the EVM to be connected to any TI MCU LaunchPad™ development kit. See

Figure 29 for names of all connections.

NOTE: Some of the header pins are not connected unless a 0-Ωoption resistor is placed.

5.2 LED Indicators Description

The EVM has multiple LEDs to notify the user what type of connection is present. The LEDs are

separated into two groups: mux control LEDs (MXCTL1-3) and status LEDs.

NOTE: The LEDs are enabled through GPIO in the pre-loaded firmware. Therefore, each must be

enabled separately if configuring a custom image (see TPS6598x Configuration GUI User

Guide and TPS65982 and TPS65986 Firmware User’s Guide).

5.2.1 MXCTL1-3 LEDs (Super-Speed Mux Contol LED)

These LEDs correspond to the GPIOs required to drive a super-speed multiplexer for the SSTX and

SSRX signals to a Type-C connector. Table 1 summarizes the LED behavior according to the type of

connection.

Table 1. MXCTLx LED Functions

LED Indicator GPIO Function

MXCTL1 GPIO_0 Plug Present

MXCTL2 GPIO_3 HD3SS460 AMSEL

MXCTL3 GPIO_6 DP Connection

5.2.2 Status LEDs

The status LEDs indicate the cable orientation, the voltage present on VBUS, and the type of connection.

The CC1 and CC2 LEDs indicate the orientation of the Type-C cable (only one of these LEDs turns on at

a time). LED A is on when 5 V is sourced on VBUS and blinks when a high-voltage contract is in place

(when acting as a source or sink of power). LED B indicates if a USB3 connection is present.

6 Using the TPS65986EVM

This section describes the EVM configurations on the pre-loaded firmware, getting started, and debugging

the EVM.

6.1 Powering the TPS65986EVM

The main power supply for the EVM is J1 barrel jack, which accepts 19 V to 20 V through a barrel jack

adaptor. The EVM can also be powered with an external power supply on TP6. The input voltage can

range to 12 V to 20 V, but the appropriate power profile for PP_HV should be configured in the firmware

using the configuration tool. The EVM can also be powered from a TI MCU LaunchPad™ development kit

by placing R30 and R31 with 0-Ωresistors. If powering with a LaunchPad™ development kit, the EVM

does not support high-voltage contracts or provide high currents at 5 V because of the limited power

capability. The EVM can also be bus powered from the Type-C connector and accepts 5 V to 20 V on

VBUS, depending on the sink configuration.

6.2 Firmware Configurations

The EVM is shipped with a preloaded firmware image that supports various Type-C and PD products. The

firmware is loaded at start-up and the configuration is defined by the state of the S2 switch (see

Section 5.1.1). The top three switches in the switch bank represent B0, B1, and B2, respectively (see

Figure 3). The top switch is used for toggling between DisplayPort configurations for 2-lane DP, USB3

multi-function, and 4-lane DP after the configuration in the table has been loaded. Table 2 lists the eight

configurations on the EVM.
